To say I am satisfied with all purchases from Military Fasteners is a bit of an understatement. Selection, price, packaging, shipping exceeds expectations. You are my number one choice for my aircraft needs, thank you, Charles

I have purchased most of my aviation needs from Military Fasteners for the last 5 years. You have provided me with the products that I have needed,with a price that is fair and a delivery on time. Thanks!

I was looking for hard to find parts for a safety critical application. The first couple of places I tried had the part on their web page but when I tried to order it they said, sorry, they did not actually have the parts. I called Military Fasteners. Talked to an employee without delay. She looked up the part number, told me who manufactured them (important), where the company is located (very important) and shipped the parts immediately from their own inventory. Super nice, helpful, efficient and knowledgeable. They get it.
